Patent FR-2215474-A1 (FR)
Title: Motor car axle housing heat treatment - to produce localised compressive stresses
IPC: C21D9/00
Filed: 1973-01-30
Abstract: Motor car drive axle housings subject to asymmetrical cyclic stresses and maximum tensile loading at the lower axle housing wall near the spring supports are heat treated by selective heating of the zones subject to low stressing to 800 to 1250 degrees C for a period during which the zones subject to max. stressing heat up by conduction to 300 degrees C max. The housings are then air cooled to room temp. within a period of >=180 secs. The axle housings may be hardened prior to the above treatment. The heat treatment is cheaper to effect than conventional heat treatment and results in improved service performance of the housings which are also easier to machine.
Patent FR-2236800-A1 (FR)
Title: Cavity insulating glass assembly - with electrically heatable cavity glass surface
IPC: C03C17/36
Filed: 1973-07-12
Abstract: One or several metal or metal oxide layers are electrically connected to Cu metallised edge zones of the sheet. These metallized zones are tinned and to these tinned layers are attached electrical connections for feeding or taking electrical current to from the conducting surface layer(s). The electrical connections are pref. applied to the tinned layer after the deposition of the surface layers on the sheet. The fluxes used for tinning have to be washed off prior to metallizing the sheet. Used for units the cavity of which can be heated to remove any moisture deposited on the interior surfaces. The procedure ensures that the metal/metal oxide layer is uniform and thus heats up uniformly.

Title: Image fading device for slide projector - has variable reflective power mirrors producing variable light through slides
IPC: G03B23/18
Filed: 1974-03-08

There are guides (7, 8) for two slides (9, 10) two total reflecting elements (13, 14) e.g. mirrors or prisms, and two variable reflecting power mirros (11, 16). There is a mirror and a total reflectory element of each optical axis with light passed through both slides to the objective. The mirrors are adjusted simultaneously so that the sum of the powers of reflection of the two mirrors is always constant, so that the quantity of light passing through one is equal to the quantity reflected by the other. Adjustment of the mirrors produces a fade between the slides.

Title: Vibration suppressor in manometer connection line - inlet and return passages of different flow resistance improve response
IPC: G01L19/00
Filed: 1974-06-19
Abstract: A device to be fitted in fluid line connected to a manometer or other pressure measuring device, permits easy flow towards the measuring device during an increase of pressure, but a high resistance to return flow.

Title: Highly stable RF oscillator - has single cavity for oscillation and stabilisation and two oscillator diodes in coaxial lines
Inventor: MARTEL JACQUES
IPC: H03B9/14
Filed: 1975-06-20
Abstract: The highly stable RF oscillator has an oscillator cavity and a stabilising cavity of large Q. These two cavities are combined into a single cavity which is matched to a source consisting of two oscillator diodes and to a load. The dimensions of the two matching circuits bear an inverse relationship to the Q of the cavity and therefore to the stability. The frequency is set using a single mechanical device. Each oscillator diode is mounted in a section of coaxial line containing a quarter-wave transformer whose secondary side is coupled to the cavity and a reflectionless termination. The cavity is rectangular and dimensioned to support the TE1on mode, where n is greater than one and increases with Q.

Title: Prepn of red and rose wines - by sepg skins from pulp and juice, and extracting colouring matter from the skins
IPC: C12H6/02
Filed: 1975-11-12
Abstract: Fermentation process for making wine from grapes having coloured skins comprises (a) de-stemming and crushing the grapes, (b) pressing the grapes to separate the juice and pulp from the skins, (c) placing the juice and pulp in a container having access to the ambient atmosphere (d) adding yeast to cause fermentation, (c) subjecting the skins to the action of an aq. mixture of (i) citric acid and (ii) hydrochloric, sulphuric or phosphoric acid until a substantial amount of colouring substance is transferred from the skins to the aq. soln. and sepg. the skins from the extract, (f) partially neutralizing the coloured extract by neutralizing the acid with a non-toxic material (g) allowing the yeast to ferment the juice and pulp to wine, with CO2 and heat being allowed to flow to the ambient atmos. and (h) adding the partially neultralized coloured aq. extract to the juice and pulp prior to the completion of fermentation. By removing the skins before fermentation the formation of a compact nut of skins on the liquid surface. The formation of a mat prevents heat and CO2 escaping which leads to deterioration of the final wine quality and may encourage the growth of undesirable bacterial. Previously the mat has had to be broken up physically and thus the present process requires less labour.
